Some landfills in larger citys have a 600 horse powered $400,000 (used) piece of machinery like this! It will grind up up your old shingles and be [partially] used in making local road ways. Unfortunately we do not have anything like this here in Tallahassee.
We at Stubbs Roofing have committed to doing our part in Tallahassee. We salvage all of the recyclable components of your old roof system.
